The invention relates to apparatus for forming lather, and it is one ofmy objects to provide an effective show apparatus for demonstrating theoperation of a latherforming device of the general type shown in my U.S. Patents 1,554,146 of September 15, 1925, 1,7 80,57 3 of November i,1930, 1,7 98,345 of March 31, 1931 and 1,7 98,346 of March 31,

A further object is to provide an apparatus which is well adapted foruse in barber shops, beauty parlors and the like to furnish lather insufi'icient quantity for shampoo pur-' poses, shaving, etc.

The lather-forming device embodies a chamber in which a saponaceousliquid is agitated by gas under pressure (preferably air) and a liquidreservoir is provided to supply said chamberwith liquid, and anotherobjectof the invention is to make novel provision whereby a constantlevel valve in a liquid supply line for the reservoir, will maintain thesame level of liquid in said reservoir and said chamber, unafiected by.the gas pressure P in the latter, which pressure is utilized for forcingthe soap bubbles through screening means to convert them into lather.

A still further object is to provide a unique construction and relationof parts in which the lather-forming device and a lather receiver areconspicuously positioned while the liquid reservoir, the gas pressuresupply means, etc, are hidden from view.

Yet another aim is to provide an apparatus which may be convenientlyconnected with a customary water system and an electric light socket toreceive therefrom the necessary water and operating currentrespectively.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplishedby reference to the accompanying drawings.

Fig. 1 is a top plan view partly broken away and in horizontal section.

Fig. 2 is a vertical longitudinal sectional view substantially on line22 of Fig. 1.

Fig. 3 is a vertical transverse sectional View substantially on line 3'3of Fig. 2.

. One form of construction has been shown for illustrative purposes, butit is to be understood that within the scope of the invention asclaimed, numerous variations may be made.

The numeral 5 on the drawings denotes an appropriate cabinet embodying ahorizontal deck 6, a front wall 7 extending downwardly from said deck,and a rear wall extending upwardly from the deck, said rear wallpreferably consisting of upper and lower sections 8 and 8 and a shelf 9,said shelf serving to support a number of the articles whose use isdemonstrated by the present invention, or to support creams, lotions,etc.

Mounted upon the deck 6, is a latherforming device 10 constructed insubstantial conformity with the devices shown by the patents aboveenumerated, but much larger for display and demonstrating pur- 7 poses.The device 10 embodies a chamber 11 for a saponaceous liquid 12, aninlet passage 13 for gas (preferably air) under slight pressure,screening means 13 which serves to condense bubbles formed in thechamber ll to a thick creamy lather, and an outlet spout 14 from saidscreening means. For de-. tails of the screening means 13, reference maybe 'hadto Patent 1,7 98,346, abovementioned. The inlet 13 is in the formof a tubul'arpost having a check valve 15 at its upper end, said postbeing surrounded by a sleeve 16suitably connected therewith at 17. Thelower end. of this sleeve is provided with a flared skirt or the like 18having radiating flanges 19 to support acake of soap 20, and if desiredthis soap cake may be confined within an openwork basket 21." he loweredge of the. skirt l8 isprovided with openings 22 for discharging andwhirling the incoming gas into the saponaceous liquid 12, therebygenerating soap bubbles in the chamber 11, and these bubbles are forcedby the gas pressure, through the screening means 135 and the spout 1 1.The gas entering through the passage 18, lifts the check valve 15, flowsdownwardly within the sleeve 16, and discharges through the notches orthe like 22, into the liquid.

Any appropriate means may be provided out pulsations, said tank beingconnected with the inlet 13 bya tube 27;

Liquid, preferably water, which may be heated if desired, is conductedto the chamber 11 by a U-tube 28 which connects at 29 with a liquidreservoir 30 which is mounted behind the wall section 8. A liquid supplypipe 31 leads to the reservoir 30 and is adapted for connection with aconventional city or other water system. A valve 32 controls theadmission of water from the pipe 31 into the reservoir 30, and saidvalve is controlled by a float 33 on a stem 34, so that the liquid isalways maintained at a constant level in the reservoir or tank 30. Theupper end of thistank is connected by a'lJ-tube 35 with the chamber 11,the chamber contained end 35 of said U-tube being immediately below thescreening means 13. Tube 35 equalizes the pressures in the upper end ofthe chamber 11 and in the reservoir 30'so that the liquid 12 in saidchamber 11, will always remain at the same level with the liquid in saidreservoir 30, the latter level being maintained by the float-controlledvalve 32.

A tray or container 36 is mounted upon the deck 6 in front of the wallsection 8 and in position to receive the lather discharged from thespout 14. Preferably, a suitable 'spillway plate 37 extends from thisspout to the container 36. The thick creamy lather discharged from thespout 14, descends in abundance into the container 36, hence welldemonstrating the use of the relatively small lather-forming devicewhich is represented by the device 10. The lather discharged may eitherrun to waste or may be utilized, for instance, for shampoo purposes,shaving, etc.

' A waste pipe 38 is shown leading from the container 36, and a waterspray pipe 39 is shown within this container for continually liquefyingthe lather and flushing it into the aforesaid waste pipe. 40 denotes'asuitable pipe for conducting water under pressure to the spray pipe 39.

It will be seen from the foregoing that a rather simple and inexpensive,yet a very efficient and attractive apparatus has been provided, eitherfor demonstrating and advertising purposes, or for use in producinglather for shampoo or other purposes.

While the general structure disclosed may gas-actuated lather-formingdevice mounted on said deck in front of said wall, a lather receivermounted on said deck in front of said wall and positioned to receive thelather discharged from said lather-forming device, a constant levelliquid reservoir mounted behind said wall, liquid-conducting andpressure-equalizing means connecting the reservoir with thelather-forming device to maintain a constant. liquid level in thelatter, gas supply means mounted in said compartment, and communicatingmeans between said gas supply means and said lather-forming device.

2. In a lather-forming apparatus, a compartment closed at its top by ahorizontal deck, a vertical wall rising from said deck, a gas-actuatedleather-forming device mounted on said deck in front of said wall, alather receiver mounted on said deck in front of said wall andpositioned to receive the lather discharged from said lather-formingdevice, a waste pipe from said receiver extending through saidcompartment, flushing means for said receiver en'ibodying a water pipeextending through said compartment, a con- 'stant-level liquid reservoirmounted behind the aforesaid wall, liquid-conducting andpressure-equalizlng tubes extending downwardly from said reservoir intosaid compartment and upwardly from said compart- J7 ment through saiddeck into said latherforming device, gas supply means mounted in saidcompartment, and a gas tube from said supplymeans extending upwardlythrough said deck into said lather-forming device.

In testimony whereof I affix my signature.
